ABSTRACT: A
series of barium-tungstate-based phosphors doped with different concentrations
of Dy3+ were synthesized by solid-state reaction method.
Photoluminescence properties and decay lifetime of Dy3+-doped BaWO4 samples were studied. The results indicated that luminescent properties of BaWO4:Dy3+ depended on the Dy3+ concentration, and the inner energy could
transfer from to Dy3+. The quality of the light
was checked by estimating CIE parameters, and the results showed that BaWO4:Dy3+ was a potential candidate as blue-green luminescent materials in white LED because
of its excellent emission spectrum excited by UV light.
